AMD Radeon HD 6320 vs AMD Radeon HD 7340

AMD Radeon HD 6320

The AMD Radeon HD 6320 (or perhaps also called ATI Mobility Radeon HD 6320) is an integrated graphics card in the Zacate netbook processor. It is based on the same graphics core as the ATI Mobility Radeon HD 4330 but without any dedicated memory. Compared to the slower Radeon HD 6310, the 6320 offers the same base clock rate, but in difference features the automatic overclocking to 600MHz (Turbo Core).

The 3D performance of the HD 6320 should be only minimally faster than a 6310 and therefore only low demanding or older games should run fluently (e.g. Call of Duty 4, Sims 3, Left 4 Dead 2, Fifa 11).

The new UVD3 video decoder allows the decoding of HD videos using the graphics card. It allows the parallel decoding of two MPEG2, H.264 and VC-1 streams and therefore compatible to BD-Live. Furthermore, the new UVD3 also supports DivX, Xvid and MPEG4 Part 2 decoding. Blu-Ray 3D via MCV (Multiview Video Coding) is theoretically supported by the UVD3 but wasn't available in the first laptops and platforms (no hardware accelleration and no HDMI 1.4 output).

AMD Radeon HD 7340

The AMD Radeon HD 7340 (or perhaps also called ATI Mobility Radeon HD 7340) is an integrated graphics card in the 2nd generation Zacate netbook processor. It is based on the same graphics core as the Radeon HD 6320, but the base clock and the turbo boost is somewhat higher. Furthermore, it features the UVD3 video processor.

The 3D performance of the HD 7340 is about 10 percent faster than the HD 6320. Gaming performance are therefore similar to a Nvidia ION or Intel HD Graphics graphics card. In our tests the HD 6320 was only able to run low end games like Fifa 11, Sims 3 and Star Craft 2 single player in lowest detail settings fluently. More demanding games like Risen or Call of Duty series were not playable.
